The Internet of Things: TU Graz researchers increase the dependability of smart systems

18.02.2019

Since 2016 a team from TU Graz has been working on dependability in the Internet of things. After having achieved remarkable success, the eponymous research project is now going into the second phase.

Smart systems are taking over the increasingly complex tasks of our private and professional daily lives. To ensure that these systems work flawlessly in harsh environments, secure and dependable solutions are required.

In the project "Dependable Internet of Things in Adverse Environments", a team from TU Graz is researching how smart systems can work reliably even under the most difficult conditions;

In the context of this funding programme, the University gives special financing to interdisciplinary projects in the field of basic research to strengthen TU Graz’s research profile and to further develop outstanding top research areas.

In the ‘Dependable Internet of Things in Adverse Environments’ project, researchers are not developing any new smart applications, but instead are ensuring that applications will work in the way they are supposed to.

‘The Internet of things is being increasingly used for security-critical applications – not only must the individual appliances work reliably in isolation, but they also have to be dependable within the overall system and communicate flawlessly,’ explains project leader Kay Römer.

Promising results as foundation stone for the second project phase

The first three years of the project yielded promising results. The team developed a positioning system which works more efficiently and accurately than the systems available today.

It ensured the cooperation in the IoT by appliances from various manufacturers using an adaptive algorithm, and protected the integrated software against security attacks. And it developed a predictive system for autonomous vehicle convoys which preemptively sidesteps dangerous situations.

New objectives for the next three years

In the last few days the research project was extended for a further three years after successful evaluation by an external jury. Now the researchers want to upscale the previous results achieved in the laboratory to the actual realities in the field, as Kay Römer explains: ‘Our approaches work extremely well on the small scale. In a dynamic system such as the Internet of things in which hundreds of billions of intelligence systems could communicate with each other in the future, the challenge is so much bigger.

In the long term, the research project is meant to develop into a research centre in which specialists from all the different areas can work together to further increase dependability in the IoT.

The lead project ‘Dependability in the Internet of things’ was granted funding of two million euros for three years in 2015. After the successful evaluation carried out by the external specialist jury, the researchers have received a one-off, follow-up funding for a further three years.

Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.

Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.

"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
